KeurSoce HDSS

The Keur Soce HDSS covers 74 villages with an estimated total population of 40,286 inhabitants within 2759 households. The Site is located in a rural area in the region of Kaolack, in the Health District of Ndoffane. The area lies between longitudes 16°00'14.8”and 16°07'13”W and latitudes 13°51'53” and 14°00'00”N. It is
located at 230 km from Dakar in the Sudano-Sahelian region of Senegal. The site's ecology is characterized by the alternation of a long and dry season from November to June and a short rainy season from July to October.

Established in 2013, the Keur Soce HDSS was set up to collect data on the population's structure, dynamics and geographical location. The Keur Soce Health and Demographic Surveillance System (HDSS) initiated its first census in 2013, followed by periodic rounds conducted to update the database. Recent rounds occurred in
2015, 2019, and 2021, with the integration of electronic data capture using REDCap software since 2015. This transition has facilitated better real-time data collection, streamlined control and utilization of previous data, and saved valuable time, contributing to the ongoing stabilization of field and management teams.
